With swsusp (kernel mode), I don't think you /can/ even hibernate to a file.

With uswsusp, the s2disk program could be patched to create a file on
demand, and it would simply exit before hibernating if not enough
space. But still, I'm not sure whether resuming from a file will work,
because the pre-resume kernel has to mount the filesystem in order to
read from the hiberfile, but the filesystem is already mounted by the
hibernated kernel...
